216 Installation & Setup Guide
I/O Configuration Type “V”
Due to the ability to select the Analog Input being used for a selected THC and the ability to configure
the Input and Output locations, no exact or standard Pinout for the THC connections is available.
Connections would be made by selecting the Analog Input for the desired THC and connecting the
Analog signals from the Voltage Divider Card. In much the same manner, the required Nozzle
Contact Sense, Nozzle Contact Enable and Hold Ignition I/O points would be selected and connected
to the corresponding appropriate pins on the Voltage Divider Card.
